Open Or Short out Wiring Harness

When the engine shows less power or does not show any power, it indicates a wiring harness issue. The first thing that needs checking is for an open or short wiring harness.

All the wire of the throttle actuator control is inside the harness together. Metal brackets in the engine can come in contact with the wiring harness. This can result in shorting out the harness.

 If the harness is melted or burned, then it needs replacing. Open the harness and fix short or open wires using electrical tape. Take the help of a professional if more than two wires are problematic.

Failed Throttle Actuator

The most common symptom of a failed throttle actuator is a stopped engine. This can also be responsible for poor fuel economy for code p2112 ford f150 Ecoboost. Internal contamination is the main reason for a failed throttle actuator. It causes the throttle valve to stop moving and harms the air supply.

Dirt and debris stored inside the actuator need deep cleaning. To fix it, open the throttle body and clean it properly. Make sure to check the inflow of air after putting everything back in place.

Bad Throttle Actuator Electrical Connection

When the engine misfires or stalling happens it reflects a bad electrical connection in the throttle actuator. This can send wrong information and cause a faulty air-fuel mixture.

It’s a bit critical to fix a bad throttle electrical connection point yourself. Take it to a professional as it’s necessary to fix the point soon. 

Throttle Position Sensor Failure

Turning on the engine light on the dashboard indicates throttle position failure. When the car computer identifies sensor failure, it signals the driver. However, lights on can indicate other issues too.

When fuel consumption is high, rough acceleration speed and the engine can result when the throttle position sensor fails.

Don’t fix the position sensor if there are other issues with your vehicle. So, it is best to immediately replace the whole sensor to avoid future issues.

Throttle Plate Stuck Or Closed

The malfunctioned throttle body can result in a stuck or closed throttle plate. Also, its common symptom is a stopped engine, or the engine is running slowly.

When the throttle plate is stuck, it will intake excess air inflow disrupting other parts. And a closed throttle plate won’t even allow the needed air to flow inside. In both cases, the engine won’t run.

Inp2112 ford f150, 5.4 throttle plate can be stuck or closed due to an incorrect angle. This can also happen for debris or dirt build-up on the throttle plate. So to fix it, clean the plate from all sides properly.
